Title: Hair brush attachable to hair dryer - has circular array of spaced longitudinal bars between which bristles protrude
Inventor: HUEBNER OTTO
IPC: A45D20/48
Filed: 1976-10-29
Abstract: The round hair brush consists of rods (1) joined together at one end so that lengthwise slits (5) are formed between the rods. The bristles of a brush of any length, consistency and quality emerge from the slits (5) so as to form a circular brush with rows of bristles. The brush is replaceable. The hair brush has a handle (6). The brush can be placed on a hair dryer, so that the hot air flows along the brush and through the inside of the rods. The rods can be made of metal or other suitable material, such as plastic. The rods are rounded on the inside. The brush has an attachment at the tip which can be removed at any time, or can be locked at the opposite end in a casing.

Title: Semiconductor store with matrix in chip - is formed so that each storage location can be addressed through row and column decoder connected in series
Inventor: RYDVAL PETER DIPL ING
IPC: G11C11/415
Filed: 1976-12-23
Abstract: A semiconductor memory has a matrix in a chip. The matrix consists of r rows and s columns, with r.s. semiconductor storage locations with two defined, different electric states. Storage locations belonging to one row or one column can be individually addressed through wires allocated to the corresponding matrix row or column, and through a first decoder selecting the row wires, and a second decoder selecting column wires. The two decoders are connected in series w.r.t. the voltage source supplying them. The decoder realising the selection according to the matrix rows and the decoder realising the selection according to the matrix columns are sequentially switched w.r.t. the voltage supply. Power loss is thereby reduced by half, while the switching delay remains the same.

Title: Spring return seat belt winder - has two reels connected with S-shaped spiral spring and inertial blocking inside spring housing
Inventor: BOTTRILL JOHN
IPC: B60R22/405
Filed: 1977-03-07
Abstract: The seat belt take up mechanism uses a spiral spring wound in S-shape onto two reels for controlled return feed action and has a ball and socket inertia blocking. The spiral spring (3) is coiled onto a working reel (1) with one end and on a feed reel (2). The connecting length of the spring forms with the two reels an S-shape. When the webbing is pulled out from the initial wound-up condition, one reel (1) rotates accordingly and the spring (3) uncoils from the reel and is taken up by the other reel where it becomes pre-stressed and provides the force which tends to return the webbing into the initial position. The housing of the reel contains an inertia blocking mechanism consisting of a ball fitted in a concave holder carrying an arm pivot on a fulcrum. The free end of the arm has a spring catch with the free end pointing towards the inner surface of a cylinder fitted with a number of teeth.

Title: Solar energy collector - formed from extruded plastic sheet with passages for heat transfer medium
Inventor: HELM SIEGFRIED ING GRAD
IPC: F24S10/70
Filed: 1977-03-14
Abstract: Solar energy collector consists of a radiator and a cover which is transparent to radiation. The individual constructional elements are extruded profiles. At least one of the extended constructional elements has projections along the edge. The collector is provided with a housing of extruded, transparent material e.g. of plastic.

Title: Track signalling system for locomotives - uses transponder recognition sequence for checking continuity of successive section signals
Inventor: HARTWIG MANFRED DIPL ING
IPC: B61L25/02
Filed: 1977-09-07
